mabuse00 Posted June 29, 2014 Share Posted June 29, 2014 (edited) It was just mentioned that sorbic acid salts can be used to make whistle mix. I thought this must be a typo, but google actually brought some hits. Potassium sorbate is readily available in the EU. Since I could not find much information, can anyone here share some experience with it?If it had advantages beside weirdo sounds it would have found some use in the pyro scene. It seems that it does not... How ist the burn rate compared to salicylate & benzoate?Is it as waxy/hard to mill down? I'm just curious Edited June 29, 2014 by mabuse00 Link to comment Share on other sites More sharing options...
dagabu Posted June 29, 2014 Share Posted June 29, 2014 75 parts Potassium Perchlorate, 25 parts Potassium Sorbate, 1 part Red Iron Oxide, 3 parts Petroleum Jelly in Colemans White Gas. My results were very similar to Benzo whistle, the tone was a bit different but the power was about the same. It's a wine clarifier and yeast stopper, it's more expensive around here and mills like potassium benzoate. Link to comment Share on other sites More sharing options...
schroedinger Posted June 30, 2014 Share Posted June 30, 2014 No worries its easy to mill down. A coffee grinder makes very fine powder out of it.Everything else like dag said Link to comment Share on other sites More sharing options...
mabuse00 Posted July 4, 2014 Author Share Posted July 4, 2014 No worries its easy to mill down. A coffee grinder makes very fine powder out of it.Have you actually tried it out? I'll have to try that sometime. That's what I like in this hobby, there's allways something to try out... Enough for a lifetime Link to comment Share on other sites More sharing options...
schroedinger Posted July 4, 2014 Share Posted July 4, 2014 Yes tried that.I got mine from brewing supplier in belgium as little pellets. Couple seconds in the mill and you get first airfloat powder Link to comment Share on other sites More sharing options...

mabuse00 Posted March 18, 2021 Author Share Posted March 18, 2021 Finally did a test last year.The food grade pellets, ground down using a kitchen blender, using oxichloride and mineral oil.Well, it made some faint noises but burned so slow that a 4x id spindled whistle motor with almost without payload did not even achieve a liftoff. I had the experience that somehow mineral oil has a strong slowing effect on my rockets, but this couldn't have been the only issue. This will be investigated futher... some time...
